Almost 8 months after the launch of RTD's Train to the Plane, a small family business owner wants a break. He says the train forces him to put his life on hold every 15-minutes.

Dan Tighe and his older brother Paul own Tighe Brothers Distillery at East 42nd Avenue and Milwaukee Street in Denver's Elyria-Swansea neighborhood.

It's next to RTD's University of Colorado A-Line, the new commuter rail service from Union Station to Denver International Airport.

Neighbors along the route hear train horns about every 15 minutes, from roughly 6 a.m. until 2 a.m. the following day.

Dan Tighe co-owns Tighe Brothers Distillery at East 42nd Avenue and Milwaukee Street in Denver. 

"It's super loud, and it's hard to do business with this type of noise,” Tighe said. “We're going on eight months now and the noise level, it obstructs our business."

Federal rules require the safety warnings when trains approach crossings.

An RTD spokesman says he sympathizes with neighbors and hopes federal 'quiet zone' designations will solve the problem.

"Our goal and target was to have quiet zones established when we opened April 22nd,” said Nate Currey, senior manager in public relations for RTD. “And so, to have it go on this long has been a challenge and frustrating for us as well. You know, if I was living there, if I was doing business there, and interrupted every 15 minutes, I would be sending emails, too."

RTD's first-of-its-kind automated positive train control system must be certified before the horns stop.

The agency hopes that will happen by the middle of 2017 at the latest.
